Waste prevention is the top priority of the European waste management strategy. In fact, as indicated in the latest Waste Framework Directive, the best option to deal with waste is not to generate it at all. In this framework, the distribution of loose dry food products through self‐dispensing systems (so‐called “loose distribution”) is being considered worldwide as a practice to reduce packaging waste generation.
This life cycle assessment evaluates the environmental convenience of the loose distribution of dry pasta, breakfast cereals and rice, in comparison with the traditional method of distribution. For each product, several baseline scenarios based on single‐use packaging were compared with different waste prevention scenarios where the product is distributed loose. The comparison addressed waste generation, thirteen impact categories on the environment and human health, and the Cumulative Energy Demand indicator.
The results are significantly different for the three products. The loose distribution of pasta allows a 50% waste reduction and a decrease in the potential impacts only when compared with single‐use cartonboard boxes. Conversely, when the comparison is made with single‐use polypropylene bags, the loose distribution can even cause an increase in waste generation (up to 15%) and in the potential life cycle impacts. For breakfast cereals, the loose distribution allows a significant reduction in both the amount of waste (up to 84%) and the potential impacts compared to the sale of traditional single‐use bag‐in‐box packages. Finally, the loose distribution of rice permits a reduction in both waste generation (up to 86%) and most of the potential impacts. In particular, the impact reduction is higher when the reference single‐use packaging that is replaced includes a cartonboard box. This article is protected by copyright. All rights reserved

It begs the question: what has changed in the world of water?There is still the same amount of water in the world today...

Incineration waste to energy means you can get FREE HEAT!
It’s true to say that the first priority of any of the industrial waste incinerators we design and manufacture is to provide an efficient, cost-effective, environmentally responsible and legally compliant waste disposal system. But, and it is a big but, our experience and technical expertise means that were appropriate and when required we can also incorporate an efficient energy recovery system into the plant. This incineration waste to energy...

Various agricultural residues have been tested as biosorbents due to their low cost, high surface area, and favorable surface chemistry. In this work, a sweet orange albedo was tested as a biosorbent for treatment of real textile effluents. The orange albedo powder was prepared by drying the residue at 50 °C and milling to 30 mesh, and then used for dye adsorption from a alkaline (pH = 10.71) effluent. The adsorption process was studied in batch experiments at 30 °C by measuring color removal and chemical oxygen...
